Cooperation with AK Transneft JSC to implement supervisory
control and data acquisition system for crude oil pipeline
system.

AK Transneft JSC is a state-owned transportation company. EleSy
started cooperation with the largest oil pipe-line operator in
Russia in 1994.

In 1995 the EleSy became the main contractor and designer of the
Transneft's SCADA.

AK Transneft's SCADA, together with facility level monitoring
and control systems, in the general case is the four-tier layered
distributed control system. The facility level involves
territorial, regional and local control systems. Preceding systems
were created at different times and were equipped with different
technical means; different software and operation systems were set
up. The AK Transneft's SCADA universalized the oil transportation
control procedure.

The Transneft oil trunk pipelines transmit about 93% of all the
oil produced in Russia; the length of the pipelines is about 48,000
km. Until now, the SCADA implemented by EleSy has had no analogues
of its scale in the world. In 1998 the EleSy received international
recognition owing to the project. The project headed the list in
the Microsoft contest.

Challenges and Scope of Work

The Transneft oil pipe-line network encompasses the major part
of the Russian territory, from Bryansk on the west to Angarsk on
the east, from Novorossiysk down south to Usinsk in the north. The
total network length is about 50,000 km.

Today the oil transportation process management involves 4,500
of automatics and telemechanics systems, 2,500 screen forms, 7,792
line pipe gate valves. Control action of such a complex Fuel and
Energy company facilities required the creation of the SCADA. It
was necessary to construct a flexible control system corresponding
to the growth dynamics of requirements and to the follow-on of
technology park of equipment.

The SCADA was initially implemented on Genesis platform
(Iconics, USA), but that control system was not able to cover the
increasing requirements. EleSy designed its own SCADA Infinity.
This system provided the sufficient level of reliability,
management and control for the oil pumping and transportation
linear part, as well as for 399 pumping stations and 856 crude
storages within the 48,000 km of the oil trunk pipeline.

All required information on the pipe-line system state passes on
the real-time basis to the main AK Transneft operation and
maintenance center in Moscow. Along all pipeline system ELSY-2000
controllers record millions of parameters responding to any process
changes within seconds.

Pipeline Application Software

Pressure control, estimation of a spillage and pipeline tapping
capability is performed by EleSy's GIDROUKLON software tool;

Implementation of Transneft's technical regulations of pipeline
operation is performed by means of EleSy's STOROZH software;

Management of crude oil tank farms is performed by EleSy's PARK
application;

The up-to-date and high-tech SCADA equipment requires
availability of efficient personnel. EleSy has training centers in
Tomsk and Moscow, where supervisors, operators, technicians and
other personnel are trained.

Results

The Transneft's SCADA system was put into commission in 1997.
The system is constantly in progress. Over the last years a lot of
new functions were realized, many advanced features were
implemented; all this made crude oil transportation more efficient
and safe.

EleSy is committed to providing comprehensive training to our
customers, whenever and wherever they need it. Every year EleSy
hosts courses and workshops either at our regional training centers
or locally or at the various plants.
